HERE’S a window into a tragedy within the American military: For every soldier killed on the battlefield this year, about 25 veterans are dying by their own hands.

An American soldier dies every day and a half, on average, in Iraq or Afghanistan. Veterans kill themselves at a rate of one every 80 minutes. More than 6,500 veteran suicides are logged every year — more than the total number of soldiers killed in Afghanistan and Iraq combined since those wars began.

These unnoticed killing fields are places like New Middletown, Ohio, where Cheryl DeBow raised two sons, Michael and Ryan Yurchison, and saw them depart for Iraq. Michael, then 22, signed up soon after the 9/11 attacks.

“I can’t just sit back and do nothing,” he told his mom. Two years later, Ryan followed his beloved older brother to the Army.

When Michael was discharged, DeBow picked him up at the airport — and was staggered. “When he got off the plane and I picked him up, it was like he was an empty shell,”
